The method outlined for the Nanostation M5 below doesn't work with the M2.
== Nanostation M5 ==
=== Firmware check failure ===
 
Flashing the Nanostation M5 (FCC ID: SWX-NSM5D) using the TFTP rescue mode will result in a Firmware check failure error.
If you attempt to flash the extender and receive a 'Firmware check failed' error, then you have a version of the NSM5 that is protected from being flashed via the default TFTP method. You will need to obtain a serial to USB interface (USB to UART TTL Module Serial Converter, 5 pin) and use it to flash the firmware.
minicom: cannot open /dev/tty8: Permission denied
Run the program so that it starts the program on the USB converter that is connected by adding `<tt>-D /dev/ttyUSB0`</tt>, and specify that it should skip initialization by adding `<tt>-o`</tt>.
You can also specify from the command line that it use the baud rate and '8N1' settings specified below by including `<tt>-b 115200 -8`</tt>.
sudo minicom -D /dev/ttyUSB0 -o -b 115200 -8
